selftests/nolibc: add new gettimeofday test cases 



These 2 test cases are added to cover the normal using scenes of
gettimeofday().

They have been used to trigger and fix up such issue with nolibc:

    nolibc-test.c:(.text.gettimeofday+0x54): undefined reference to `__aeabi_ldivmod'

This issue happens while there is no "unsigned int" conversion in the
coming new clock_gettime / clock_gettime64 syscall path of
gettimeofday():

    tv->tv_usec = ts.tv_nsec / 1000;
